Angelique Limoges and Rosalia de Catargena are selected to compete in a Queen Examination, a unique test to determine the most suitable candidate for the cosmic throne. Tasked with developing their own continents on a distant planet, the girls must nurture these lands into prosperous civilizations and vibrant ecosystems. Assisting them in this challenge are nine Guardians, each wielding power over elemental forces like fire, wind, and water, guiding the girls in their quest for queenship.
